Abstract
Abstract An antifouling coating composition having superior antifouling properties and stability over an extended period of time, said composition comprising (A) an antifouling agent composed of (i) 10 parts by weight of a triphenyltiin compound of the formula ##STR1## wherein Y represents --OH, halogen, ##STR2## and (ii) 10 to 60 parts by weight of cuprous oxide and/or cuprous thiocyanate, (B) a resinous vehicle composed of a resin having an acid value of not more than 10 as a main ingredient, and (C) an organic solvent, said resinous vehicle being present in an amount of 6 to less than 10 parts by weight per 10 parts by weight of the triphenyltin compound, said antifouling agent amounting to 37 to 75% by weight based on the weight of the coating composition, and said composition having a pigment volume concentration of 50 to 80% by volume.
